Description

Technical Field

[0001] This utility model belongs to the field of RV technology, and in particular relates to a flip-up step mechanism and vehicle. Background Technology

[0002] In the RV sector, because their body design is usually higher than that of ordinary family cars, and the interior space layout needs to meet diverse needs such as living and resting, the vehicle body is relatively high off the ground. This means that users often need to use a step mechanism as a transition support when getting in and out of the vehicle.

[0003] However, the step mechanisms used in traditional RVs have obvious limitations: some steps fixed to the bottom of the vehicle will increase the width of the vehicle during driving, not only taking up space, but also making it easy to collide with road obstacles, affecting the vehicle's passability and driving safety; while some electrically retractable steps can solve the space occupation problem, they rely too much on a single electric drive system. Once the electric components (such as motors, push rods, etc.) fail, the steps cannot be deployed or retracted normally, directly causing users to be unable to get in and out of the vehicle. This problem will greatly reduce the convenience and reliability of RV use, especially for the elderly, children or people with mobility impairments. Utility Model Content

[0004] The purpose of this utility model is to provide a flip-up step mechanism and vehicle to solve the problems mentioned in the background art of traditional RV step mechanisms, which are either fixed and occupy space, affecting passability, or rely solely on a single electric drive, which are prone to failure and prevent users from getting on and off the vehicle normally, thus easily causing poor convenience and reliability of RV use.

[0005] To achieve the above objectives, the specific technical solution of this utility model is as follows: a flip-type stepping mechanism includes two sets of inner side plates arranged symmetrically, and multiple pedals are arranged sequentially from top to bottom on the opposite side of the two inner side plates. Multiple sets of flip-type stepping mechanisms are movably and inclinedly arranged below the inner side plates, and the multiple sets of flip-type stepping mechanisms flip outward to form usable steps.

[0006] Preferably, a rear plate is fixedly connected to one side of the two inner side plates, wherein a bottom plate is fastened to the bottom of the inner side plates by bolts, and the bottom plate, the rear plate and the two inner side plates cooperate to form a space for assembling multiple pedals.

[0007] Preferably, an electric push rod is provided on the rear side of the rear plate, and the electric push rod serves as the driving structure of the inner plate, used to drive the inner plate to flip. Specifically, a rod sleeve is integrally connected to the lower part of the rear plate surface, and a rotating rod is movably arranged on the inner surface of the rod sleeve.

[0008] Preferably, a plurality of pedals are provided below the inner side plate, wherein each pedal has a connecting plate sleeved on both ends, and the two connecting plates are located on opposite sides of the two inner side plates, wherein the ends of the connecting plates are connected to movable shafts; and mounting grooves are provided on opposite sides of the two inner side plates.

[0009] Preferably, a ratchet is fitted onto the surface of the movable shaft, wherein the ratchet is engaged with a pawl.

[0010] Preferably, one end of the pawl is connected to a connecting rod, wherein the other end of the connecting rod is movably mounted in the inner cavity of the mounting groove via a bearing, and a coil spring is mounted on the surface of the mounting groove.

[0011] Preferably, a pull plate is sleeved on the surface of the connecting rod, and a pull rod is connected to one end of the pull plate, wherein the bottom of the pull rod extends to the bottom of the inner side plate.

[0012] Preferably, a blowing mechanism for blowing dust off the pedal surface is provided on the rear side of the rear plate and on the side of the electric push rod. The blowing mechanism includes a fan as a power source for blowing air and an air blowing pipe assembly installed on one end of the pedal to pressurize and spray air.

[0013] Preferably, the input end of the fan is shielded from dust and impurities in the air by a filter screen, and the filter screen is movably connected at the input end of the fan, so that the filter screen can be removed to clean the dust on its surface. Meanwhile, the output end of the fan is connected to an air inlet pipe, the output end of the air inlet pipe is connected to a distribution pipe, and the output end of the distribution pipe is connected to several branch pipes.

[0014] On the other hand, this utility model also provides a vehicle with a flip-type step mechanism, including a vehicle body, wherein a body is mounted on the frame of the vehicle body, and a door is movably connected to the front side of the body via a hinge.

[0015] The flip-type step mechanism and vehicle of this utility model have the following advantages: This flip-type step mechanism uses two sets of inner side plates and multiple pedals to form a multi-section step, with a rear plate and bottom plate for auxiliary fixed assembly. The electric push rod serves as the driving structure, with its two ends movably connected to the bottom wall of the vehicle body cavity and the outer wall of the rear plate, respectively. When the user controls the extension and retraction of its output end, the rear plate and the rod sleeve can be pulled to flip around the rod as a fulcrum, thereby driving the inner side plates and pedals to flip. When the electric push rod cannot drive, the flip-type pedal mechanism under the inner side plate can be used. The pedal is installed through a connecting plate and a movable shaft, and achieves unidirectional movement with the cooperation of a ratchet and a pawl. Pulling the pull rod can cause the pawl to disengage from the ratchet, and the pedal flips outward until the connecting plate and the abutment seat are in a horizontal state for use. In addition, in the blowing mechanism on the rear side of the rear plate, the fan delivers airflow to the blowing pipe group through the air inlet pipe and the air distribution pipe to blow away dust on the pedal surface. The mud scraper on the front side of the bottom pedal can scrape mud stains off the user's shoes. Attached Figure Description

[0024] To better understand the purpose, structure, and function of this utility model, the following detailed description of a flip-type stepping mechanism and vehicle of this utility model is provided in conjunction with the accompanying drawings.

[0025] like Figures 3-10 As shown, the present invention discloses a flip-type step mechanism, comprising two sets of symmetrically arranged inner side plates 200. Multiple pedals 220 are arranged sequentially from top to bottom on opposite sides of the two inner side plates 200. The two ends of each pedal 220 are fixedly connected to opposite sides of the two inner side plates 200. The inner side plates 200 and pedals 220 cooperate to form a multi-section step for the user to step on to enter the vehicle body 110. A rear plate 230 is fixedly connected to opposite sides of the two inner side plates 200, and the rear plate 230 is fixedly welded to the two inner side plates 200, increasing the assembly strength among the three. A base plate 240 is bolted to the bottom of the inner side plates 200. The base plate 240, rear plate 230, and two inner side plates 200 cooperate to form a space for assembling the multiple pedals 220.

[0026] like Figure 4 As shown, an electric push rod 300 is provided on the rear side of the rear plate 230. The electric push rod 300 serves as the driving structure for the inner side plate 200 and is used to drive the inner side plate 200 to flip. The electric push rod 300 is located inside the cavity opened at the bottom of the vehicle body 100 and is inclined. Its two ends are respectively connected to the bottom wall of the cavity of the vehicle body 100 and the outer wall of the rear plate 230 through bearings.

[0027] Specifically, a rod sleeve 320 is integrally connected to the lower part of the surface of the rear plate 230, and a rotating rod 310 is movably provided on the inner surface of the rod sleeve 320. The rotating rod 310 passes through the outer plate 210 and is movably connected to the vehicle body 100 through a bearing.

[0028] When the output end of the electric push rod 300 is extended or retracted by the user, it can pull the rear plate 230 and the rod sleeve 320 to rotate around the rotating rod 310, thereby driving the inner side plate 200 and the pedal 220 to rotate.

[0029] like Figure 5 and Figures 7 to 10 As shown, this solution is equipped with a manual flip-type pedal mechanism. When the electric push rod 300 cannot drive the pedal 220 to flip for use, the flip-type pedal mechanism is temporarily used to assist the user in getting on and off the vehicle. Multiple sets of flip-type pedal mechanisms are tilted and movable under the inner side plate 200. These multiple sets of flip-type pedal mechanisms flip outward to form usable steps. When the pedal 220 loses its function and cannot be flipped for use normally, the flip-type pedal mechanism can be manually unfolded for use, improving the convenience of daily use.

[0030] Multiple pedals 500 are provided below the inner side plate 200. Each pedal 500 has a connecting plate 510 sleeved on both ends. The two connecting plates 510 are located on opposite sides of the two inner side plates 200. The ends of the connecting plates 510 are connected to movable shafts 520. Specifically, the two inner side plates 200 have mounting grooves 201 on opposite sides for mounting structures such as the movable shaft 520, ratchet 530, and pawls 531.

[0031] Two inner side panels 200 are provided with outer side panels 210 on opposite sides. Adjacent inner side panels 200 and outer side panels 210 are fixedly connected by connecting plates. Multiple abutment blocks 211 are connected from top to bottom at the rear ends of opposite sides of the two outer side panels 210. Adjacent abutment blocks 211 and adjacent outer side panels 210 are integrally formed. After the rear plate 230 is pushed by the electric push rod 300 to drive the inner side panels 200 and the pedal 220 to flip out, the abutment blocks 211 can abut against the outer wall of the front side of the cavity of the vehicle body 100, thereby helping to increase the stability of the inner side panels 200 after flipping. The cavity of the vehicle body 100 has an opening that is smaller than the diameter inside the cavity.

[0032] A ratchet 530 is fitted on the surface of the movable shaft 520, wherein the ratchet 530 is engaged with a pawl 531, and the shaft end of the movable shaft 520 is movably mounted in the inner cavity of the mounting groove 201 through a bearing. With the combined cooperation of the ratchet 530 and the pawl 531, the movable shaft 520 can only move in one direction.

[0033] One end of the pawl 531 is connected to a connecting rod 540. The other end of the connecting rod 540 is movably mounted in the inner cavity of the mounting groove 201 via a bearing. A coil spring 541 is mounted on the surface of the mounting groove 201. The other end of the coil spring 541 is also mounted in the inner cavity of the mounting groove 201. When the connecting rod 540 is pulled to rotate, the pawl 531 can be rotated to disengage from the ratchet 530. The coil spring 541 can be stretched outward to store force. After the connecting rod 540 is released, the coil spring 541 can drive the connecting rod 540 to reset, which in turn drives the pawl 531 to reset and engage with the ratchet 530.

[0034] A pull plate 551 is fitted on the surface of the connecting rod 540, and a pull rod 550 is connected to one end of the pull plate 551. The bottom of the pull rod 550 extends to the bottom of the inner side plate 200. When the user pulls the pull rod 550, the pull plate 551 can be tilted downward, which in turn causes the connecting rod 540 to rotate, which in turn causes the pawl 531 to disengage from the ratchet 530. This releases the pawl 531 from the ratchet 530, so that the pedal 500 can be restored to its original state when not in use. Furthermore, the bottom of the inner side plate 200 and the outer side plate 210 on opposite sides are connected to abutment seats 560. Abutment seats 560 are used to limit the connecting plate 510. When using the pedal 500, in order to prevent the user from pulling the pedal 500 out of the horizontal position, abutment seats 560 are specially designed. When the pedal 500 is rotated, it rotates around the movable shaft 520, and the connecting plate 510 will also tilt and rotate with the pedal 500 until one side of the rotating connecting plate 510 is in contact with the adjacent surface of the abutment seat 560, so that the pedal 500 can no longer rotate. At this time, the pedal 500 is in a horizontal position, and the pedal 500 can be used in this way.

[0035] The surface of the abutment seat 560 has a through hole for the pull rod 550 to pass through, and the bottom of the pull rod 550 is connected to a handle for the user to pull the pull rod 550.

[0036] Furthermore, the surface of the pedal 500 is provided with anti-slip texture to prevent slipping when the user steps on the pedal 500.

[0037] like Figures 3 to 6 As shown, a blowing mechanism for blowing dust off the surface of the pedal 220 is also provided on the rear side of the rear plate 230 and on the side of the electric push rod 300. The blowing mechanism includes a fan 400 as a power source for blowing air, and an air blowing pipe assembly 430 installed on one end of the pedal 220 for pressurizing and spraying airflow. The air blowing pipe assembly 430 is a pressurizing nozzle.

[0038] As a further optimization of this solution, such as Figure 3 and Figure 7 As shown, a mud scraper is connected to the front side of the end of the pedal 220. When there is mud on the sole of the user's shoe, the mud can be scraped off by the mud scraper before stepping on the pedal 220.

[0039] The mud scraper can be installed on the front side of multiple pedals 220. In this solution, it is preferred to install one mud scraper, which is located at the bottom pedal 220.

[0040] Specifically, the input end of the fan 400 is shielded from dust and impurities in the air by a filter screen. The filter screen is a movable connection at the input end of the fan 400, and the filter screen can be removed to clean the dust on its surface. Specifically, the output end of the blower 400 is connected to an air inlet pipe 410, which consists of a fixed pipe and a telescopic hose. The fixed pipe is connected to the output end of the blower 400, while the telescopic hose is connected to the air inlet end of the distribution pipe 420. By using a fixed pipe and a telescopic hose for the air inlet pipe 410, interference with the movement of the air blowing pipe assembly 430 and the distribution pipe 420 when they rotate with the inner side plate 200 can be avoided.

[0041] Specifically, the output end of the air intake pipe 410 is connected to the air distribution pipe 420, and the output end of the air distribution pipe 420 is connected to several branch pipes, which connect to the air blowing pipe assembly 430. In this solution, the material of the air distribution pipe 420 and its branch pipes is not further limited. Both the branch pipes and the air distribution pipe 420 in this solution can be flexible hoses or rigid pipes. The specific selection can be made according to actual needs.

[0042] In actual use, the blower 400 draws in air and delivers it to the air blowing pipe group 430 through the air inlet pipe 410 and the air distribution pipe 420. Finally, the pressurized airflow is sprayed out through the nozzle of the air blowing pipe group 430 to clean the dust and debris remaining on the surface of the pedal 220 after being stepped on.

[0043] On the other hand, such as Figure 1 and Figure 2 As shown, this utility model also provides a vehicle with a flip-type step mechanism, including a vehicle body 100. A body frame 110 is installed on the frame of the vehicle body 100. The body frame 110 is stably connected to the frame of the vehicle body 100 through a specific connection structure. The connection structure between the body frame 110 and the vehicle body 100 includes, but is not limited to, welding, bolting, or riveting, to ensure that the body frame 110 and the vehicle body 100 can withstand various stresses and vibrations generated during vehicle operation. The installation position of the body frame 110 should match the center of gravity of the body frame 110 with the overall design center of gravity of the vehicle body 100 to ensure the stability of the vehicle during operation.

[0044] The working principle of the flip-up step mechanism is as follows: When the flip-up step mechanism of this RV is working, the two sets of inner side plates 200 and multiple pedals 220 cooperate to form a multi-section step, with the rear plate 230 and the bottom plate 240 assisting in the fixed assembly; the electric push rod 300 serves as the driving structure, with its two ends movably connected to the bottom wall of the cavity of the vehicle body 100 and the outer wall of the rear plate 230, respectively. When the user controls the extension and retraction of its output end, the rear plate 230 and the rod sleeve 320 can be pulled to flip around the rotating rod 310 as the fulcrum, thereby driving the inner side plates 200 and the pedals 220 to flip; when the electric push rod 300 cannot be driven, the part below the inner side plate 200 can be used. The flip-type pedal mechanism has a pedal 500 mounted via a connecting plate 510 and a movable shaft 520. With the cooperation of a ratchet 530 and a pawl 531, it can achieve unidirectional movement. Pulling the lever 550 can cause the pawl 531 to disengage from the ratchet 530, and the pedal 500 flips outward until the connecting plate 510 and the abutment seat 560 are in a horizontal position for use. In addition, in the blowing mechanism on the rear side of the rear plate 230, the fan 400 delivers airflow to the blowing pipe assembly 430 through the air inlet pipe 410 and the air distribution pipe 420 to blow away dust on the surface of the pedal 220. The mud scraper on the front side of the lowest pedal 220 can scrape away mud stains on the user's shoe soles.

[0045] like Figure 1 and Figure 2 As shown, the front side of the vehicle body 110 is movably connected to a door 120 via a hinge. The specific installation position of the door 120 depends on the layout of the vehicle body 110 within the vehicle body 100. When the box of the vehicle body 110 is located on the side of the vehicle body 110, the box door is installed on the corresponding side of the vehicle body 110 via a hinge or other rotating connection device, allowing the box door to be opened and closed by rotation, enabling access to the space inside the box. When the box is located at the rear of the vehicle body 110, the box door is also installed at the corresponding position at the rear of the vehicle body 110 via a suitable rotating connection device. The installation of the box door should ensure that it does not interfere with other parts of the vehicle body 110 during opening and closing, and should also have good sealing and locking functions to prevent items from falling out and external debris from entering the box.

[0046] The flip-up step mechanism involved in this solution is installed on the front side of the vehicle body 100, and located below the door 120; the vehicle body 100 has a cavity reserved for the flip-up step mechanism to flip 90 degrees, such as... Figure 1 As shown, the flip-up step mechanism is in the unfolded use state after being flipped outward by 90 degrees. When it is not in use, the flip-up step mechanism is flipped in the opposite direction by 90 degrees, so that the bottom surface of the base plate 240 is in front, and the flip-up step mechanism is flipped into the cavity of the vehicle body 100. The base plate 240 then flips over and blocks the opening of the cavity of the vehicle body 100.

[0047] In the specific design, longitudinally, the flip-up step mechanism should be located under the vehicle body 110 between the front and rear wheels of the vehicle body 100, providing a convenient position for passengers to get on and off the vehicle; laterally, the distance of the single-sided flip-up step mechanism extending beyond the side of the vehicle body 110 should be less than or equal to 50mm and should not exceed the width of the vehicle, in order to comply with relevant safety and regulatory standards. The flip-up step mechanism is connected to the vehicle body 100 through a sturdy installation structure, such as by bolt fastening or welding, to ensure that the flip-up step mechanism is stable and reliable during vehicle operation. The step surface should have an anti-slip design, and its edges should not have any sharp protrusions that may cause injury, such as sharp corners or sharp edges.

[0048] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
